Check the back of the ECU port to see if any of the contacts have pushed out the back of the socket. Good luck!

My 2004 Suzuki Aerio will not start


the scanner drops out when the power voltage drops too low.
so your 12vdc the ECU is tool low. use volt meter
to find the voltage drop point.
you mean no spark, fire is what fuel does when ignited.
and spark is first. if no spark say, i have no spark to 4 cylinders.
my guess is this.
lost DC power to ECU.
this kills spark
and loss of spark kills injection so, lost power kills injection 2 ways.
find this problem by watching spark and power to ECU.
the ECU will drop out about at 9v.
cranking the voltage usaully sags to about 11v cranking.
now you have a goal 11v min, to ECU at all times.(cept siberia)

Cannot locate data link connector


If you're looking for the OBD 2 port for your scanner - there isn't one. OBD 2 scanners / code readers only work/are used by 1996 and newer vehicles. I also have a 95 JGC and I have to resort to the "lamp flash" method to get the trouble codes from the ECU.

If you hear relays clicking sometimes and the jeep won't start, at those times, is the check engine light illuminated on the dash, or not? If no check engine light is on the dash, at times when the jeep won't start, your ecu is in need of repairs. The ecu sends power to the ignition and fuel relays and when the ecu starts to malfunction, the relays usually start clicking.

I have a Honda Oddysey 1998, and in the scanner show the code P1607


P1607 Engine Control Module (ECM)/Powertrain Control Module (PCM) Internal Circuit Malfunction.

aquire the appropriate pinout diagram for your ecu's plugs. then proceed to verify each of the ecu's power wires have the correct voltage. then proceed to perform a continuity test on all ecu grounds. this means checking voltage from the ecu plug to the ground location that the wire goes to. you should find your problem somewhere within there if you have already swapped out with a KNOWN GOOD ecu.

How to scan the 2001 daewoo nubira fault codes.


Your port should be located under the dash on the driver's side near your knee area. The port should be pointing straight down from the dash. The scanner will be plug and play and you shouldn't have to jump and pins for the OBD-II port. As for the codes, there are so many thousands of codes that you can't even guess what codes will be generated from your scan

Will not stay running


a compression check should be done to make sure that it is not a compression issue, also you can plug in a node light in place of the injector to see if the ECU is firing it off, then check for spark at the plug,

there is very little you can do by pulling out the ECU, most of the diagnostic work on the ECU is done through the OBDII port using a scanner,



hope this helps
